Cancellation Controller Based on Fuzzy Relational Matrix and Comparison with Other Control Algorithms

IFAC Proceedings Volumes, 1994
Abstract In the paper the cancellation controller based on the inverse fuzzy relational model is presented. The inverse fuzzy relational model is obtained using the input error model. The proposed algorithm is implemented on nonlinear process which has varying time constant and the process gain according to the operating point. The comparison between

Reconstruction of PET Images with a Compressed Monte Carlo Based System Matrix - a Comparison to Other Monte Carlo Based Algorithms

IEEE Nuclear Science Symposium Conference Record, 2005, 2006
A new method to compress the system matrix of a PET scanner calculated by Monte Carlo (MC) simulations is introduced. The proposed method reduces the size of the matrix drastically and allows a considerable reduction in the number of simulated particles.
